Most comic strips run out of creative energy after their initial inspiration. Trudeau has just kept improving, year after year, in part because he stays so close to changing events. He still has his ear for the way young people talk through all the varying slang fashions (perhaps helped by his children). At any rate, he has never been better than in the last six years. B.D., who always wore his football helmet when he was not wearing an army helmet in Vietnam, goes to Iraq as an aging National Guard adjunct and his tank is hit by an IED. The strip blacks out, and when he emerges from the darkness, he is seen for the first time without a helmet of some kind—and we find his hair is white at the temples. But that is the least shock—he has also lost a leg. The beloved original character of the strip is tragically maimed.
